The year is 1931. Prince Tokugawa Yoshinobu holds absolute control over Japan. Remnants of the Meiji era’s culture can be seen around the city, but scientific technology and Japanese esoteric cosmology Onmyodo are also developing. Yet lurking behind the glitz is Kuchinawa, a dissident group planning the assassination of the prince. Tasked to extinguish these dissidents is Nue, the government’s secret executioner group. Sawa Yukimura, who works for this organization, suffered at the hands of the Kuchinawa boss. Her entire family was murdered and she dedicated her life to avenging their death.

Class 1-A visits Nabu Island where they finally get to do some real hero work. The place is so peaceful that it's more like a vacation … until they're attacked by a villain with an unfathomable Quirk! His power is eerily familiar, and it looks like Shigaraki had a hand in the plan. But with All Might retired and citizens' lives on the line, there's no time for questions. Deku and his friends are the next generation of heroes, and they're the island's only hope.

A mysterious group called Humarize strongly believes in the Quirk Singularity Doomsday theory which states that when quirks get mixed further in with future generations, that power will bring forth the end of humanity. In order to save everyone, the Pro-Heroes around the world ask UA Academy heroes-in-training to assist them and form a world-class selected hero team. It’s up to the heroes to save the world and the future of heroes in what is the most dangerous crisis to take place yet in My Hero Academia.
